4. JLB / S/WAVES / 2008.07420 / STEREO SWG / Paris-Meudon / - 4 - S/WAVES instrument status Both instruments continue to function nominally We continue to see lots of “dust” –especially prominent and puzzling on A. The operations team at APL continues to give very good service: –in getting bits to the ground; –in getting commands sent up; –in dealing with "situations" from time to time.

5. JLB / S/WAVES / 2008.07420 / STEREO SWG / Paris-Meudon / - 5 - Calibrations and direction finding status Inter calibration between receiver 1 & 2, on STB Fundamental for direction finding (Auto & cross-correlations between two antennas) Ratio close to 1 Agreement to about 0.5 dB
